ER, MASSACHUSETTS, A CORPORATION OF .wrnnine mAcHiNE- Application filed December 8 ,1922, Serial No. 605,657.;

To all whom it may concern:

Be it known that I, ELBRIDGE R. HOLMES,

a citizenof the United States, residing at Worcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Winding Machine, of which the following is a specification. I This invention relates to awinding machine ofgeneral application but particularly adapted for winding the warp spools used in narrow ware looms. It isjdesirable that such spools be wound under relativelyheavy pressure, which pressure must be relieved or released when a full spool is to be removed and replaced. l y Y 4 It is the general obj ect, of my invention to provide an improved device for thus applying and releasing the pressure on. the spools. A further object is to provide means for holding the tension devices in operative o inoperative position, as desired.

An important feature of my invention also relates to the provision of an equalizing device, by the use of which tension may be applied to either cylindrical or tapered spools.. I Further features of my invention will be hereinafter described and more particularly pointed out in the appended claims.

' A preferred form of the invention is shown in the'drawings, in which 7 Fig. 1 is a side elevation of myimproved winding machine; v

Fig. 2 is a rear elevation thereof; Fig. 3 is a plan view of themachine;

Fig. 4 is a detail sectional elevation taken along the line 4-4: in Fig. 1; and

Fig. 5 is a detail sectional elevation, taken along the line 5-5 inFig. 3.

Referring to the drawings, I have shown my improvements applied to a winding machine which is in general of a common type.

a The machine as shown comprises end frames 10 and 11 held in suitable spaced relation by cross rods 12 and supporting a driving shaft 13 in bearings 14; Tight and loose pulleys 15 and 16 are provided on the driving shaft '6 a, wind g drum .21] nib n e ya Spo 2 r st po -medium '2 and re 11 ,tated thereby. These spools may be either of; the usual cylindrical shape or of the slightly: tapered shapeshown in the drawings. A'hand Wheel123 on the-shaft 2O is provided for occasional manual rotation of .the drum 2l. 'A second shipper handle 24 'may also be provided at'the front of the ma ing pressure to the spools 22. The spools 22 l have PIQJBOtlDg bearings or gudgeons at their ends adapted to be receivedin bearing recesses inthe underside of tension arms 25, these recesses beingopen' -attheir under sides. The arms 25. arepivoted at the ends of an equalizinglever 26 which in turn is pivoted on .a stud 2,7 fixed in a collar28 .mounted on one of the cross rods 12 of the machine frame. Stop arms 29 are also 3djustably secured toithe cross rod 12 and limit angular equalizing movement of the lever26.

A tension device is provided at each side of the machine forapplying heavy down:

ward pressure to each arm 25. Each of these devices comprises anarm 30 (Fig. 1), connected at its outer end by a pin 32 to the lowerend of a weight rod 33 upon which any desired number of removable weights 34 maybe placed. The upper end of each rod 33 is pivotally connected by a cross pin 35 (Fig. 4) to a supportingmember '36.

r A grooved roll 37 is mounted on a stud 38 fixed in the member 36and engages the upper edge of thecorresponding tension arm, 25, thus transferring the downward pull of the weights 3L-to the armsv 25 which, in turn, press downward upon the gudgeons or bearings of the spool 22 which is in the machine. v

Each arm 25 is provided with two openings 39 and 40 and the member 36 is provided with a locking pin 41 mounted to slide transversely and to enter one or the other of the openings 39 and 40. The member 36 may thus be locked in the operative position shown in full lines in Fig. 1 or in the inoperative position shown in dotted lines in said figure.

A spring actuated latch 4-2 is provided for manually withdrawing the locking pin 41 and for yieldingly advancing the pin to locking position. Projections 923 are provided on the arms 25 to limit movement of the members 36 in both directions, and .handles 44 on the ends of the arms 25 permit the operator to raise the arms to release the spools when desired.

Having described the details of construction of my improved machine, I will now point out its advantages in operation zf The usual running position of the parts is shown in full lines in Fig. 1, with the members 36 locked in the forward position. With the parts thus disposed, the weights 34 exert their weight upon the -bear ings of the spool 22, thus causing the spool to be wound under heavy pressure. When it is desired to remove and replace a full spool, the locking pins 41 are withdrawn by means of the latches 42 and the members 36 are then pushed backward on the arms 25 to the position shown in dotted lines in Fi 1.

In this position the weights 34 are supported directly over the pivots of the arms 25, and the arms may be readily lifted by the handles 44: without raising the {heavy weights 34-. The labor involved in removing and replacing a full spool is thus greatly reduced, as only the light arms 25 needbe raised.

The equalizing lever 26 permits the ma chine to be used with either tapered or cylindrical spools and equalizes the pressure upon the two ends of the spool.

Having thus described my invention and the operation and advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is 1. In a winding machine, a winding drum, a spool supported in rolling cont-act with said drum, pivoted bearing members for said spool, and means to apply pressure to said bearing members, said pressure ap plying means being movable to transfer the pressure to points adjacent the pivoted support of said members and to thereby render said pressure applying means inoperative.

2. In a winding machine, a winding drum, a spool supported in rolling contact with said drum, pressure arms having bearings for said spool, and means to apply pressure to each arm, said pressure means being movable to operative and inoperative positions on said pressure arms.

3. In a winding machine, a winding drum, a spool supported in rolling contact with said drum, arms having bearings for said spool, means to apply pressure toeach arm, said pressure means being movable :to operative and inoperative positions on said arms,jand locking devices for said pressure means.

4. In a winding-machine, a winding drum, a spool. supported in rolling contact with said drum, arms having supports on said machine and having bearings ior said spool, weighted rods supported on said arms, and means permitting shifting of said rode on said arms to selected positions-adjacent 'to or removed from the points of support of said arms.

5. In a winding machine, a w-indingdrum, a spool supported in rolling conta'ct' with said drum, arms having supports on said machine and having bearings for said spool, weighted rods supported on said arms, means permitting shifting of said rods on said arms to selected positions adjacent to or removed from the points of support of said arms, and means to hold said rods in said selected positions.

6. In a winding machine, a wind ng drama,

a spool supported in rolling contact with said drum, pivoted pressure arms having bearings for said spool, a pair of weighted members, a supporting roll for each meniber mounted for movement along one of said pressure arms, and means to secure each of said members in selected positions on said arms adjacent to or removed from the pivots of said pressure arms. 7

7 In a winding machine, a winding drum, a spool supported in rolling Contact with said drum, pressure arms having bearings for said spool, a pair oi weighted members, a guide roll on each member supported on one of said pressure arms, stops for said rolls on said arms, and locking devices to position said members onsaid arms, said members being movable on said arms to operative or inoperative position thereon.
